Despite their fractured marriage, the pair maintained a seemingly ideal co-parenting arrangement—sharing custody and even taking family holidays together. Tune in to explore the tangled web of relationships, motives, and secrets that may finally reveal what drove Erin Patterson to the edge.

What drives a seemingly normal mother to poison her former in-laws? The question haunts Lisa from the Mushroom Murder Trial, and in this second episode examining Erin and Simon Patterson, we might finally have found the answer.

Simon's emotional testimony in court revealed surprising details about their relationship after separation in 2015. Despite their marriage breakdown, they maintained what appeared to be an ideal co-parenting arrangement—sharing custody equally, taking family holidays together, and even involving each other in major life decisions. Simon continued to help Erin with her dream home build, using his engineering expertise while she pursued various educational interests from veterinary science to legal studies.

But beneath this cooperative veneer lurked a disturbing truth. Psychological research shows poisoners typically display childlike, manipulative personalities, desperate for control and avoiding direct conflict. Erin fits this profile perfectly—fabricating medical concerns including false claims about ovarian cancer, regularly visiting her mother while simultaneously claiming childhood abuse, and maintaining a façade of normalcy that masked her growing resentment.

The catalyst? A seemingly minor dispute over Simon's tax status that Erin claimed affected her family benefits. This "beginning of the end" escalated beyond reason, eventually leading to the calculated mushroom poisoning that shocked Australia. With only 11 homicides involving extended family members occurring annually nationwide, and men responsible for 88% of these crimes, Erin Patterson stands as a truly unusual case—perhaps someone simply "born this way" rather than shaped by circumstance.
